Mk4 Anatomy, Part 2: A Look Under the Hood of the Summit Racing Mk4 Project

Like the Mk4 you see above?

You can duplicate it using the Factory Five components covered in our Mk4, Part 1 post, along with the parts listed below from Summit Racing.

Summit Racing has even taken the time and hassle out of ordering the parts by creating special combos just for the build. That means you’ll spend less time tracking down parts and more time doing car guy stuff you actually enjoy—like wrenching on your Mk4.
